A seven-meter-tall “pyramid” formed by 109 water tanks gained quite a bit of attention at Jiangjian Park in Wuxi on 18th March. When night falls, the lights on the water tank pyramid are switched on, forming a unique scene along the ancient canal of Wuxi. Jiangjian Park was originally a small island, on which there were clusters of pottery shops. People used to stack up pottery tanks to save place and put on candles or lights on them. Gradually it became an important folk ritual in Wuxi, which could even rival the Dragon boat races.
